FORMATTING YOUR PAPER: All text must be in a two-column format. The
total allowable width of the text area is 6-7/8 inches (17.5 cm) wide by
8-7/8 inches (22.54 cm) high. Columns are to be 3-1/4 inches (8.25 cm) wide,
with a 5/16 inch (0.8 cm) space between them. The main title (on the first
page) should begin 1-3/8 inches (3.49 cm) from the top edge of the page.
The second and following pages should begin 1.0 inch (2.54 cm) from the top
edge. On all pages, the bottom margin should be 1-1/8 inches (2.86 cm) from
the bottom edge of the page for 8.5 x 11-inch paper; for A4 paper, approximately
1-5/8 inches (4.13 cm) from the bottom edge of the page.

TYPE-STYLE AND FONTS:

Wherever Times is specified, Times Roman may also be used.
If neither is available on your word processor, please use the font
closest in appearance to Times that you have access to. PLEASE DO
NOT USE ANY RYUMIN FONTS.

MAIN TITLE. Center the title 1-3/8 inches (3.49 cm) from
the top edge of the first page. The title should be in Times 14-point,
boldface type. Capitalize the first letter of nouns, pronouns, verbs,
adjectives, and adverbs; do not capitalize articles, coordinate
conjunctions, or prepositions (unless the title begins with such
a word). Leave two blank lines after the title.

AUTHOR NAME(s) and AFFILIATION(s) are to be centered beneath
the title and printed in Times 12-point, non-boldface type. This
information is to be followed by two blank lines.

The ABSTRACT and MAIN TEXT are to be in a two-column format.
The ABSTRACT is to be in fully-justified italicized text, at the
top of the left-hand column, below the author and affiliation information.
Use the word "Abstract" as the title, in 12-point Times, boldface
type, centered relative to the column, initially capitalized. The
abstract is to be in 10-point, single-spaced type. The abstract may
be up to 3 in. (7.62 cm) long. Leave two blank lines after the Abstract,
then begin the main text.

MAIN TEXT. Type main text in 10-point Times, single-spaced.
Do NOT use double-spacing. All paragraphs should be indented 1 pica
(approximately 1/6 inch or 0.422 cm). Be sure your text is fully
justified -- that is, flush left and flush right. Please do not place
any additional blank lines between paragraphs. Figure and table captions
should be 10-point Helvetica (or a similar sans-serif font) boldface
type; callouts should be 9-point Helvetica, non-boldface. Initially
capitalize only the first word of section titles and first-, second-, and
third-order headings. FIRST-ORDER HEADINGS. (For example, 1. Introduction)
should be Times 12-point boldface, initially capitalized, flush left,
with one blank line before, and one blank line after. SECOND-ORDER
HEADINGS. (For example, 1.1. Database elements) should be Times 11-point
boldface, initially capitalized, flush left, with one blank line before,
and one after. If you require a third-order heading (we discourage it),
use 10-point Times, boldface, initially capitalized, flush left, preceded
by one blank line, followed by a period and your text on the same line.

FOOTNOTES: Use footnotes sparingly and place them at the bottom of
the column on the page on which they are referenced.

Use Times 8-point type, single-spaced. To help your readers, avoid
using footnotes altogether and include necessary peripheral observations
in the text (within parentheses, if you prefer, as in this sentence).

REFERENCES: List and number all bibliographical references in 9-point
Times, single-spaced, at the end of your paper. When referenced in the
text, enclose the citation number in square brackets, for example [1].
Where appropriate, include the name(s) of editors of referenced books.
